I'm not sure thats necessarily as bad as it sounds.
First of all, the major beneficiaries were people who were the wealthiest and can afford not to reduce their useage - many of whom NEED to be reducing their useage due to energy security / global warming.
Second of all, the exact wording is the energy price guarantee will only remain universal. Key word. Universal. That means it could be means tested and still available to those on lower income.
Thirdly this needs a bit of context.
About 45mins before his statement this was tweeted:

Some really good news for Chancellor Hunt. Big fall in gas prices today. NatWest estimates that if the Dec '22 contract hits 300p/therm the Energy Price Guarantee becomes cost neutral. i.e. the new government's biggest spending outlay is shrinking rapidly $GBP
See graph
The gas price is currently at 403p.
Now we could see more spikes in price, however the markets seem to think there is going to be less issues with gas - indeed if demand is lower, that will keep prices lower - again it comes back to getting rich high energy users to reduce how much they consume.
So, whilst I think this announcement is extremely frightening, I also think its NOT as bad as it might sound and it is recognising that the wealthiest were benefiting most from the policy.
The people who are most vulnerable are middle earners with mortgages with high LTV.
However this response should also help to stop interest rates spiraling quite as much as the government don't have the financial black hole that the markets were terrified of.
A lot of it is arse about face and not without risk. But I think people need to stop, and work out what the knock on effects of this are and what it actually means.
